The Valve Guide is a cylindrical component that acts as a support for the valve stem. Its main function is to guide the valve's movement as it moves up and down during operation. The outer diameter of the valve stem and the inner diameter of the guide is set to allow the valve to slide up and down without any friction. The valve guide also keeps the valves cool by dissipating the heat that is generated by conducting it away from the valve. They are usually made from bronze or steel.

Over time, the valve guides can become worn out due to friction between moving valve stem and the inner surface of the guide. This will cause the air/fuel mixture or the exhaust gases to leak out of the chamber. In addition, it would also cause external contaminants and unmetered air to enter the combustion chamber. These contaminants would affect the air/fuel ratio and internal vacuum, causing the engine to run below its efficiency.

If your exhaust fumes have a trace of blue in them or if your catalytic converter has a rotten egg smell due to carbon-clogging, it is likely that a damaged valve guide is the culprit. You should replace a defective valve guide to prevent your engine from deteriorating further and eventually breaking down.
